6 people stuff flyers into 500 envelopes in 5 minutes. They all work at the same rate.
From the question you can ascertain that if the number of people stuffing the Flyers into the envelopes increases the number of minutes they can stuff this Flyers in the envelopes decreases. Therefore the relationship between the number of people stuffing the envelopes and the number of minutes it takes to stuff the flyers in the envelope is an Inverse relationship. In other words the number of people stuffing the envelopes is inversely proportional to the number of minutes required to stuff the flyers into 500 envelopes . Mathematically,
Looking at the relationship 6 people takes 5 minutes . If the number of people decreases the number of minutes will increase. Therefore, 3 people which is half the number will take double the time which is 10 minutes . 1 person will take 6 times the time which is 30 minutes. Similarly, 2 people will take 3 times the time which is 15 minutes.
